I don't think I have ever described any company as a 'Class Act' but this guy deserves this accolade for sure. Communication from before sending in the injections through to the detailed report and despatch details was excellent and honest. Thanks James & Sian.

Great communication, helpful when encountering issues and process is both easy and efficient. Wish I had used the service before I found out the painful way my injectors were duff! Back on track now, thanks!
